Grading and Drainage a. Engineering Design Report Appendix A Storm Water Design Calculations – The calculations in the drainage report do not include all of the regraded contributing area. The applicant must include the pond areas and all other regraded areas in the calculations. RESPONSE: The stormwater design calculations have been revised to include all pond surfaces and regraded contributing areas – See Design Report Appendix A. b. Civil Design Drawings Sheet C4.2 – It is not clear where the overflow discharge goes after exiting the short drainage ditch. Please note if the discharge enters an existing swale that carries runoff around the building. RESPONSE: After retaining the design storm, pond overflow from larger storm events and some run-off from unaffected existing areas will follow the existing flow path around the north side of the building – See note added to sheet C4.2. c. Civil Design Drawings Sheet C4.1 – The applicant must indicate where the retention pond on the northwest portion of the site will overflow and where that overflow discharge will be directed. RESPONSE: After retaining the design storm, overflow from the NW retention pond will be directed via stabilized rock weir and drainage ditch to an existing swale on the east side of the trail that flows north and eventually enters the roadside ditch near the intersection of Deadman’s Gulch and N. 19 th Ave. – See notes added to sheet C4.1.
